Title: Germanium amplifier
Post by: Simon123 on October 14, 2013, 07:25:02 pm

Hello!
I have found this circuit on net, but now i only have AC542, could this be substitute for AC152.
I can get AC543, but i was just wondering if this could do it?

Just one question: why?

The AC542 is much weaker than AC152. I don't think it's a good replacement. Better use an AC128. But AC152 are available on Ebay Germany.

This amplifier will sound terrible. If you want to know how bad early transistor amps sounded then build one.

Ok, tnx in my local shop they have a lot of germanium transistors so i dont need ebay.
I built this and it doesnt sound terible https://sites.google.com/site/elektronikasimon/germanium-transistor-amplifier   .
Why? Beacuse they are avilible-cheap and i wana try out something difrent.

And when i build it, ill post video to youtube and link on this page, so everywhone can see.

Ok, we have a very different meaning of terrible sound.
